Our invention relates to a window frame and sash and the objects of our invention are: [First, to] To provide a window frame and sash comprising a frame having resilient portions in which the sash may be frictionally engaged and securely held therein against displacement. [Second to] To provide a window frame and sash of this class in which the sash may be snapped into the frame whereby force tending to remove the sash from the frame causes increased tightening of the sash in frame. [Third, to] To provide a window frame and sash of this class which is very versatile in fitting the window openings in wall studding whereby ample tolerance is provided for the accommodation of considerable discrepancies. [Fourth, to] To provide a window frame and sash of this class which saves considerable time of the builder in installing windows in the walls of a house or the like. [Fifth, to] To provide a window frame and sash of this class which is very easy to install and which very efficiently excludes the elements from the interior thereof. [Sixth, to] To provide a window frame and sash of this class which promotes the complete finishing of buildings preliminary to the installation of the sash which may be snapped to the frame after all other finishing work has been completed. [Seventh, to] To provide a window frame and sash of this class incorporating a frame having a channel portion surrounding the same in which plaster or stucco may be very efficiently interlocked rendering the window weatherproof and preventing the cracking of plaster around the frame, which frame also includes a circumferential nailing flange forming the rear n all of the channel portion and by which the frame is secured to studding or the like, said frame also including inwardly-extending flanges forming a rectangulurly shaped and forwardly-facing abutment; this abutment functions as a rectangulnrly shaped stop for the rearwardly-focing abutment surrounding and forming a part of a second window frame. [Eightl], to] To provide a window frame and sash of this class which is very simple and economical in construction, efficient in operation and which will not readily deteriorate or get out of order.

With these and other objects in view, as will appear hereinafter, our invention consists of certain novel features of construction. combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon forming a part of this application in which: Fig. l is a side elevational view of our window frame and sash, Fig. 2 is a fragmentary sectional view taken from the line 22 of Fig. 1 showing the same on a large scale and illustrated by dash lines the relative positions of wall studding and plaster and Fig. 3 is a similar view of Fig. 2 illustrating a fixd sash only and showing by dash lines the positions of the sash before interlocking with the frame during the assembly thereof.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawings.

[The frame 1, snap-in frame 2, sash frame 3. window panes 4 and 5, hinges 6 and 7 and the drip cap 8 con stitute the principal parts and portions of our window frame and sash. Referring to the accompanying drawings it will be seen that the frame 1 is composed of a plurality of straight sections connected together at miter joints of corners of the frame. The cross-sectional arrangement of the frame 1 as shown in Fig. 2 of the drawings provides an extended nailing flange la having openings lb therein to which nails may be projected into studding as illustrated by dash lines A, Fig. 2 of the drawings.

Integral with the nailing flange la and forming a part thereof is the channel shaped structure 10 which provides for the interlocking relationship of plaster as illustrated by dash lines C relative to frame 1.]

Referring to the accompanying drawings, it will be seen that the frame 1 is composed of side sections connected with one another at the top and bottom by top and bottom sections. These sections are connected together at mitered joints at the corners of the rctangularly-shnped frame. The cross sectional arrangement of any one of these sections is shown in Fig. 2 Each of these sections of the rectanguIarly-shaped frame is provided with an outwardly-extending nailing flange la, having openings 1b therein, through which nails may be projected into the studding, as illustrated by dash lines A in Fig. 2 of the drawings. Thus the four sections form an outwardlyextending circumferentially-disposed nailing flange. Each section includes a forwardly-extending flange ]g which merges with an outwardly-extending flange 1 h. It will be observed that the flanges Ia and 1']: are arranged substantially pamllelly of one another. However, flange la extends outwardly a greater distance than the flange lh to provide clearance for hammering nails in position. The flanges Ia, 1g, and 1h provide a circumferential channel 1c in which plaster or stucco established interlocking relationship with the frame I, as illustrated by dash lines C. Each section of the frame also includes a rearwardly-extending portion 1k which may be said to be a rearward continuation of flange 1g, and the inwardlyextending portion is indicated at 1m. The inwardly-extending portions 1m of the frame sections form 0 rectangulorly-shaped, forwardly-facing abutment In. At the upper horizontal portion of the frame 1, secured to one leg of the channel-shaped in cross-section structure It: is the drip cap 8 which is a straight angularly-extending member having a clipped portion 8a frictionally engaged with the leg of the channel-shaped portion 1c which extends outermost and in spaced relationship from the flange la, it being noted that this drip cap 8 is adapted to shield the frame 1 from water which runs down the outer surface of the plaster c of the window frame 1. [Integral with the nailing flange 1a and the channel-shaped structure 1c is an extending resilient inclined portion 1d having a relatively thin edge 1e which is engageable with a corner bead portion 2a of the snap-in frame 2, or as shown best in Fig. 2 of the drawings] Portions Id extend rearwardly and inwardly from the inner edge of the flange portion 1m. These portions Id are resilient and are provided with a relatively thin edge I e at the extreme rear thereof. It will be noted that the inclined portion 1d is r extended around the four sides of the frame 1 so that these inclined portions ld converge inwardly toward each other and are relieved from each other at the corners of frame 1 so that they may be readily deflected outwardly by the bead portions 2a of the snap-in frame 2 when said snap-in frame 2 is moved from the dash line position as shown in Fig. 3 of the drawings. to the solid line engaged positions wherein the snap-in frame 2 is frictionally en- 3 gaged in the frame 1 at its bead portions 2a by the edge 1c of the inclined portions 1d. The rectangular frame 2 is Z-shaped in cross section.

This frame includes an outwardly-extending section forming a rectangularly-shaped and rearwardly-facing abutment 2b, which is disposed in confronting relationship with the forwardly-facing abutment In of the main frame I. Adjacent to the inclined portions 1d is an offset portion 1f which provides for the placement of mastic 9 between the frame 1 and the snap-in frame 2. The sash frame 3, shown in Fig. 2 of the drawings, is formed of a similar extrusion or section to the snap-in frame 2 and as shown in Fig. 1 of the drawings this sash frame 3 is hinged by the means of hinges 6 and 7 to the snap-in frame 2. It will be noted that the sash frames 3 and the snap-in frame 2 are substantially Z-shaped in cross-section and provided with accurate bead portions at their corners. These accurate bead portions 23. serve to strengthen the sections and also provide for the interlocking of the snap-in frame 2 with the edge 1c of the frame 1 as hereinbefore described. It will be noted that 2 planes of the Z-shaped in cross-section frame members 2 and 3 as shown in Fig. 2 of the drawings bear against each other when the sash frame 3 is closed relative to the snap-in frame 2 which provides for an efficient weather seal. As shown in Fig. 3 of the drawings, the glass pane 4 is secured in the snap-in frame 2 by means of putty 4a, while the arrangement, shown in Fig. 2 of the drawing, illustrates the secondary sash frame pivoted to the snap-in frame 2, thus the window pane 4, if desired, may be secured by putty or otherwise into the snap-in frame 2 if it is not desired to provide for ventilation through the particular window.

The operation of our window frame and sash is substantially as follows: The liberal extension of the nailing flange la of the frame 1 provides for the adaptation of the frame 1 to openings within the studding A which may vary a considerable amount without being critical to the proper securement of the frame 1 within the wall opening. The nailing flange 1a is secured to the studding as illustrated by dash line A in Fig. 2 of the drawing by positioning a nail in the opening lb and driving the same into the studding A. It will be noted that several of these openings lb are provided in the nailing flange portions 1a of the frame 1 for securely connecting said frame 1 to the wall studding A as desired. The channel portion 1c provides an interlock for the plaster as illustrated by dash line C and its extended leg forms an edge over which the clipped portion 8A of the drip cap 8 may be secured as desired. The drip cap 8, when fixed to the leg of the channel portion 1c extends outwardly and downwardly and provides a rain shed for the frame 1, all as shown in Figs. 1 and 2 of the drawings. The portion of the frame 1 extending from the nailing flange inwardly to the edge 1e, as hcreinbefore described, is resilient so that the inclined portion 1d may be deflected outwardly when the snap-in frame 2 is forced inwardly from the dash line position to the solid line position as shown in Fig. 3 of the drawing. As the bead portions 2a slide past the inwardly-extending edge portions of the inclined portions 1d which converge toward each other the edge portions 1e move inwardly beyond the bead portions 2a and securely lock the snap-in frame 2 within the outlines of the frame 1 so that pressure exerted on the snap-in frame 2 toward the dash line position, as shown in Fig. 3 of the drawings, causes the inclined portions 1d to be forced inwardly into binding position against the bead portions 2a whereupon the snap-in frame 2 is more securely held in proportion to the force applied which tends to remove it to the dash line position 3; thus the snap-in frame 2 is very securely held in the frame 1 and the mastic 9 in the offset portion 1d of the frame 1 provides for a water-proof seal of the snap-in frame 2 against the frame 1 which excludes the elements from the interior of the frame 1. The double bearing of the sash frame 3 relative to the snap-in frame 2 at the parallel portions of the Z-shaped in crosssection frames 2 and 3 provide for efficient sealing against the elements so that a very efficient window frame and sash is provided employing the structure as shown in Fig. 2 of the drawings. The structure shown in Fig. 3 of the drawings, together with the pane 4 and putty 4a, provides for an equally efficient seal as hereinbefore described in connection with the structural arrangement as disclosed in Fig. 2 of the drawings.

It will be here noted that the sloping portions lg and 1k of the frame 1 serves as a sill for the window which provides for drainages and installation economy.

Though we have shown and described the particular construction, combination and arrangement of parts and portions, we do not wish to be limited to this particular construction, combination and arrangement but desire to include in the scope of our invention the construction, combination and arrangement substantially as set forth in the appended claims.
